Hi!

Do you have any idea how to control the microphone? I'd like the audio source to be microphone on headset (not the built in one). So I run alsamixer, set everything in "capture" section to zero... and I still get the audio from the internal microphone :-(.

Tested with arecord | aplay.

Any ideas?

Hi! Try to set Jack Function to Headset or enable b HS Mic.

I can't find "b HS Mic" function. I can set "Input Select" to "ADC", and ten internal microphone is off, but I can't get any audio on input. I tried with "Jack function" both "headset" and "headphone".

Do I need to enable microphone bias voltage somewhere?

Best regards, Pavel
